10.8. Performance-Based Bitumen Selection

Try these first

1. 1.

   What does PG stand for in binder selection?

   Hint

   Think about what the purpose of such grades might relate to.

2. 2.

   Why is performance-based selection important?

   Hint

   Consider pavement durability.

3. 3.

   What does PG stand for?

   • Performance Grade
   • Performance Gauge
   • Grade Performance

   Hint

   Focus on the significance of grade in material performance.

4. 4.

   True or False: Performance-based selection only considers laboratory performance.

   • True
   • False

   Hint

   Think about how we choose materials based on actual scenarios.

5. 5.

   You are designing a pavement for a region with high temperatures and heavy traffic. Which PG grade would you advise selecting, and why?

   Hint

   Think about the extreme temperatures the material must face.

6. 6.

   Evaluate the potential pitfalls of using an older bitumen grading system in modern pavement design.

   Hint

   Consider how material performance has changed over time.
